scientists believe that germinating radish seeds give off a chemical that interferes with the germination of other seeds. A few years ago‚ a group of scientists published a scientific paper that demonstrated that germinating radish seeds have an allelopathic effect upon lettuce seeds. A year later‚ another group of botanists repeated the experiment. The second group claimed that the radish seedlings had no allelopathic effect upon lettuce seed germination or growth. Now it is your turn to determine

Introduction Seed germination and growth are influenced by many factors. Some of these are the environment‚ light quality and moisture availability. Other factors which may influence seed germination are a result of the environment surrounding the seed‚ like alleleopathy. In this experiment we are going to study the alleleopathy of garlic. Using the scientific method of inquiry‚ my group and I are experimenting if the volatility of the crushed garlic will affect germination and growth of the

In this lab the peroxidase enzyme is tested in a dormant avocado seed as well as an avocado seed undergoing the process of germination. A gas pressure will be used to test the seeds and see if the peroxidase enzyme is present in either of the seeds. A catalyst is very similar to track spikes. Spikes increase a runner’s speed‚ as a catalyst speeds up the chemical reaction time in a plant. Neither the catalyst nor shoes are changed in these actions. Enzymes are macromolecules that act like catalysts

a species can produce chemicals that can prevent the growth or germination of another species. An example of this is Australian native plants such as Casuarinas and Eucalypts which produce allelochemicals that prevent competition of other plants. This is a form of a defence mechanism in order to survive. A negative effect of Allelopathy includes Patterson’s Curse. Patterson’s curse releases allelochemicals that inhibit the germination and growth of other plants. When plants are competing they compete

"To examine the effects of salinty on fenugreek seeds." INTRODUCTION Since the arrival and settlement of European farmers two hundred years ago‚ dryland and irrigated-land salinity have become problematic for the Australian environment‚ despite the fact much of our natural landscape is naturally saline. The response of plants to salinity has been explained as a two-phase growth response. The first phase of growth reduction is characterised by osmotic stress due to salts in the outside solution

PROPOSAL I. PROBLEM What is the role of sunlight on the germination of Vigna radiata (Mung bean) seed? II. TITLE The role of sunlight on the germination of Vigna radiata seed. III. RATIONALE The germination of the seed is a physiological event. The light is one of the most important environmental factors for germination of seeds. The seeds of many species do not germinate in the dark. Vigna radiata seed or Mung bean seed as it commonly called will be used for the study since it can

granted. Without them‚ much of the world would be different and it would affect the planet in a negative manner. Therefore‚ it is necessary for plants to be able to grow. In this paper‚ there is information on seed germination and light’s effects on plants. These are important part of seeds’ growth and they were a part of the experiment that was performed and then analyzed in this paper. The experiment tested the color of light’s effect on an Alaskan pea plants’ growth throughout the course of fourteen

Zea mays L. Ten seeds for each level of gamma radiation (0 krad‚ 10 krad‚ 30 krad and 50 krad) were planted and tested for the number of germinating seeds and plant height‚ using a meter stick or ruler. Data were collected for 30 days period and graphs and figures of the data were analyzed. Therefore‚ it can be inferred that the level of gamma radiation introduced to the plant would have adverse effect on the growth of corn plant; in terms of plant height‚ number of germinating seeds and its over-all

has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions‚ while do slow growth of a seed‚ they do not kill the seed. A seed can be dormant for a majority of its lifespan‚ seeds watered with acid solutions stayed in a dormant condition. For example‚ trial three (3) part one (1) and two (2) both experienced germination. Whereas
